Virtual hosts help us organize the development of applications by local domain names, these names will not be available on the internet, that is, they only exist on our machine, because the browser first consults the hosts file of the operating system, and later, solves the domain and IP in the large network; Thus, it is possible to host different sites with their respective domain name and pointing to the same IP, in this case, localhost (127.0.0.1). Examples of common names in development:

  • myapp.local
  • myapp.test
  • myapp.app

Once the style is chosen, you can create your virtual hosts:

  • calculator.app
  • portfolio.app
  • landing.app

This article focuses on Debian and its derived distributions, such as Ubuntu, Mint, and more. Apache version 2 is required to be installed on the system and the rewrite module is enabled. If the rewrite module is not enabled, you can use the following command:

sudo a2enmod rewrite
sudo service apache2 restart

Step by Step

For the creation of virtual hosts, it is necessary to do it with root user permissions:

sudo su
cd /etc/apache2/sites-available/
ls -l

The contents of the folder will be something like this:

-rw-r--r-- 1 root root 1234 jul 16 2018 000-default.conf

Now, copy the default file and assign the name that the virtual host will have:

cp 000-default.conf app.con

With the preferred text editor, modify the content:

# Gedit editor
gedit app.conf
# Sublime editor
subl app.conf
# VS Code editor
code app.conf

At the end of editing, the content should look very similar to this:

<VirtualHost *:80>
	ServerName app.dev
	ServerAlias www.app.dev

	ServerAdmin webmaster@localhost
	DocumentRoot /var/www/app/public

	ErrorLog ${APACHE_LOG_DIR}/error.log
	CustomLog ${APACHE_LOG_DIR}/access.log combined

	<Directory /var/www/app/public/>
		Require all granted
		AllowOverride All
		Options -Indexes +FollowSymLinks +MultiViews
	</Directory>
</VirtualHost>

The project is hosted in the app folder, and public is the public directory. After saving, enable the site on the server:

a2ensite app.conf
service apache2 restart

Finally, register the virtual host in the hosts file:

gedit /etc/hosts

Add the following lines and save:

120.0.0.1    app.dev
120.0.0.1    www.app.dev

Use cases

In the Laravel case, it is very good to have a virtual host, since you can make the browser reload when you make changes to the project; To do this, you must add the local domain name in the Laravel Mix configuration:

# webpack.mix.js
mix.js('resources/js/app.js', 'public/js')
   .sass('resources/sass/app.scss', 'public/css')
   .sourceMaps()
   .browserSync('app.dev');

Save and run the server with NPM:

npm run watch
